A video guide from Holden Vintage & Classic. We hope this will help to explain enough for you to make a decision that best suits your requirements.
Shown here is an introduction to our full distributor rebuild service - an explanation of dwell angle and the advantages of replacing points (in effect a switch that burns itself out) with two alternatives that do not wear.
Lumeniton Electronic ignition - optically switched
Lumeniton Magnetronic Ignition - magnetically switched (see • Fitting the Lumenition... )
Lumenition optically-switched contact breaker replacement ignition systems consist of two basic models, the Optronic ignition system and the Performance Ignition system.
The installation of both systems is straight forward and easily reversible, involves no specialist tools and is normally completed in less than an hour.
Both systems replace the distributor contact breakers with an optical switch (using a separate, distributor-specific fitting kit) and an external power module. The same distributor-specific fitting kit is used for both models and the optical switches differ only in the connectors used with the different power modules.
The system works by creating a beam of light inside the distributor which is broken by a fan-like part (called a chopper) fitted over the distributor cam. As the distributor cam rotates, the chopper breaks the beam of light and the optical switch and external power module fires the coil. The spark is distributed to the plugs through the distributor cap and rotor arm as usual.
